I suck at describing anything, hence the beautiful diagram provided. I've been taking cracks here and there trying to break it down, get the little bits and pieces of this working before diving into the whole thing to very mixed results.

Yes, I was consumed by the ro-sham-bo minigame brainrot that were in a handful of GBA games. Some guidance would be much appreciated
